红外线：从碳弧灯或氙弧发出的不可见的、长波长的辐射，它对胶片和设备传送热量。
Infrared: Nonvisible, long wavelength radiation from a carbon or xenon arc that contributes to the heating of the film and equipment.
这些水冰屑都太细小，无法散射长波红外线，却能够反射可见光，特别是光谱中波长较短的蓝光。
They are too small to scatter long-wavelength infrared light, but visible wavelengths can bounce off the particles - especially at the shorter blue end of the spectrum.
